Was the Revolution justified?

I'm unsure which revolution you're referring to. There have been more than one through out human history. A few include the French Revolution, the American Revolution, the Chinese Revolution, and even the Haitian Revolution.

Explanation:

What I can tell you however, is that revolutions are and can be justified, because they are a good way to get your point across about an injustice that may be occuring to you and a significant number of other people like you. Revolutions have long been used to revolt and rebel against corrupt governments who've tried to use their power to limit or even suppress people's natural rights, in order to control them. So, in my opinion, though the excess violence should be unnecessary for change, if done successfully Revolutions can have the potential to positively affect the conditions and circumstances of many groups of people who are currently being mistreated.

it would be  

germany had to pay all damages related to the war.

and i think

germany had to take sole responsibility for the war.
